Question

An 80 kg Rottweiler needs 40 mL/kg over 12 hours. What's the flow rate per hour?


A. 3,200 mL/hr
B. 267 mL/hr
C. 3.3 mL/hr
D. 133 mL/hr

Answer 1

Answer:

The flow rate is 267ml/hour

Step-by-step explanation:

Hello, great question. These types are questions are the beginning steps for learning more advanced Equations.

To solve this we first need to find out how many ml the Rottweiler needs over 12 hours. We do this by using the Rule of Three property.

$\frac{40ml}{1kg} = \frac{x}{80kg}$

$\frac{40ml*80kg}{1kg} =x$

$3200ml = x$

So the Rottweiler needs 3200 ml over a 12 hour period. We now need to find the flow rate per hour. We can solve this by simply dividing 3200 ml by 12 hours.

$3200ml / 12hours = 266.67ml/hour$

So the flow rate is 267 ml/hour (rounded to the nearest whole number)
